The line of symmetry of the parabola whose equation is y = ax2 - 4x + 3 is x = -2. What is the value of "a"? -2 -1 -1/2
iren2701 [21]

Answer:

a = -1.

Step-by-step explanation:

y = ax^2 - 4x + 3

Convert to vertex form:-

= a(x^2 - 4/a) + 3

= a [ (x - 2/a)^2 - 4/a^2 ] + 3

From this we see that the line of symmetry is y = 2/a so

2/a = -2

-2a = 2

a = -1.

Maria is on a hike. If she hikes to the scenic lookout on the following map first, she will have to hike farther than if she
iren [92.7K]

Based on the distance to the end of the hike and the distance to the scenic lookout, we can calculate that the straight route is 2 km shorter than the scenic lookout route.

<h3>Which route is shorter for Maria?</h3>

If Maria took the straight route to the end of the Hike from the coordinates, (4, -4) to (-5, 5), she would have to walk 13 km.

If she went the scenic lookout route, she would have to first go to (2,3) before going to (-5,5) which is 15 km.

The difference is:

= 15 - 13

= 2 km

A more readable version of the question is:
Maria is on a hike. If she hikes to the scenic lookout on the following map first, she will have to hike farther than if she went straight to the end of the hike.

3 connected points on a coordinate plane. The point labeled, "Maria," is at 4, -4. The point labeled, "end," is at -5, 5.

A solid line connect the points "Maria" and "end." The point labeled, "scenic lookout," is at 2, 3. Dashed lines connect "Maria" to "scenic lookout" and connect "scenic lookout" to "end."
